Keywords:
assessment experiments and simulations, motions in waves, Naval platform, transient maneuvering
Background:
AVT-161, -216, -280, and -348 and international CFD and maneuvering workshops T2015 and SIMMAN20 have progressed from experimental and simulation capability for course keeping (including heavy weather) and steady state turning maneuvering in calm water and waves, which has provided physical understanding and guidance for naval ship design, simulation best practices, and standardization of naval ship maneuvering requirements. All of which well positions the community of interest to tackle the grand challenge of transient maneuvers.
Objectives:
1. Leverage/extend current steady state maneuvering physical understanding and experimental and prediction capability for grand challenge of transient maneuvers: (i) zigzag; (ii) stopping by propeller reversing; (iii) acceleration turning; and (iv) backing motion with steering. (i) and (ii) include calm water and waves, whereas (iii) and (iv) will focus on calm water.
2. Investigations of unsteady 3D vortex onset, progression, and interactions; hull, propeller, and rudder and ship motions and wave boundary-layer and wake interactions; effects of environmental conditions (waves and headings).
3. Advancement of experimental and prediction capability and physical understanding.
4. Assess physics and measurement and prediction capability for NATO STANAG mission-oriented transient maneuvering criteria (also hold discussions on acceptance criteria with national and international collaborations), including scale effects via full scale CFD. Explore opportunity to obtain sanitized full scale trail data via national and international collaborations.
5. Improve/develop RoM using multi fidelity and ML&AI via international collaborations.
6. Collaboration with other AVT working groups and international workshops.
7. Provide capability for improved naval ship designs and aid for standardization activities.
Topics:
-Identify validation metrics and assess the capability of simulation tools to predict the maneuvers. Provide insight into any discrepancies and input to improve simulation capabilities.
-Quantify scale effects on some of the maneuvers.
-Physics of unsteady 3D vortex onset, progression, and interaction; hull, propeller, and rudder interactions; effects environmental conditions (waves and headings).
